Ok, so I have purchased a nice set of e60 M5 wheels for my 535xi Sport project,...you know the one! It's my project car that I want to build up as the '10 version of the F90 M5,..wannabe! Thus far, I have MHD Stage 1, and I plan to get to Stage 2,..but with larger Catalytic converter,....as I must be smog legal in VA. I digress,...so, I have my e60 M5 wheels,...Style #166, and they have regular valve stems, which also means they don't have TPM sensors. So, the first step in mounting the tires will be to source a set of TPM sensors. I'm thinking I need to get a set of TPM sensors for a 2010 535,...that will definitely mount on BMW Style #166 wheels!

Hmm, that's a thought! But then again,...I'd be peeping at a glaring TPMS warning light! Plus,...at time of State inspection,...the vehicle most likely wouldn't pass because of the TPMS light being on. But thank you all the same....

Early E60s use ABS/DSC controller to detect flat tires, later E60s have a TPMS sensor integrated into the valve stem. If you leave them out, you're going to be driving around with a TPMS fault staring at you every. single. time. you drive the car. Annoying to say the least.

. I then created a Tire Size spreadsheet in Excel,...to capture the difference in circumference ratio between the Front and Rear tires and the revolutions per/mile difference based on data from the Mfr (source: Tirerack). I discovered the following:

e60 (2010) 535xi Sport #166 / 19" Wheels C-Difference = .138 Revs per mile difference = 3
The tires sample I used on Tirerack registered the same "Circumference",...however, my spreadsheet still shows a 3 miles in revs per mile (805 vs 808),...which is the same for the Stock setup.

In none of your calculations are you taking offset into consideration. That will be your biggest issue with OEM M5 wheels on an AWD E60.
